Solar microgrids so radiotherapy, pathology and drug fridges never lose power
Cancer units in poorer countries lose treatment days, spoil drugs and damage machines during power cuts. Solar panels with batteries sized for the cancer unit would remove that failure point.
Voltage instability and outages shorten linac component life, interrupt fractions, spoil temperature-sensitive drugs, and halt slide processing. Hospital solar microgrids with battery storage are now cost-competitive with diesel in most of Africa and South Asia. Designing the microgrid specifically for the cancer unit's load profile, with the linac on a conditioned circuit, is a bounded engineering project with quick payback.
Hypothesis
Cancer units on a dedicated solar-plus-battery microgrid will cut power-related treatment interruptions by at least 80% and reduce linac component failures within two years compared with grid-plus-generator units.
Rationale
Off-grid solar transformed vaccine cold chains and rural clinics; the same approach applied to the highest-value equipment in a hospital has an obvious return.
What would test it
Install at five units, log outages, interruptions, fraction completions, and component replacements before and after, alongside fuel-cost savings.

Bottlenecks it attacks
- Most of the world has almost no cancer care · Seven in ten cancer deaths happen in low- and middle-income countries, where radiotherapy, pathology, surgery and drugs are scarce.
